Overview

Synflex 275mg Tablet contains naproxen sodium 275mg, a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation from conditions such as osteoarthritis, rheumatoid arthritis, mild to moderate menstrual (period) pain, muscle strains, and other musculoskeletal aches. It works by reducing the body’s production of prostaglandins, the chemical messengers responsible for pain, swelling, and fever.

On DoctorOnCall, Synflex 275mg Tablet is supplied as a prescription medicine, and an online consultation is required so a doctor can review your medical history — including any history of stomach ulcers, kidney or heart problems, or use of blood thinners — before this product is prescribed and dispensed, to ensure it is used safely for your specific situation.

How it Works

Naproxen works by blocking cyclo-oxygenase (COX) enzymes, reducing the production of prostaglandins that cause pain, inflammation, and fever in the body. This helps reduce swelling and provide sustained pain relief for several hours per dose.

Directions for Use

Take Synflex 275mg Tablet exactly as prescribed by your doctor, swallowing the tablet whole with a full glass of water, preferably with food or milk to help reduce stomach irritation. Avoid lying down immediately after taking the tablet, and do not crush or chew it.

Dosage

The dose and frequency of Synflex 275mg Tablet will be determined by your doctor based on the condition being treated and your individual risk factors, commonly taken as one or two tablets at a time, up to a defined maximum daily dose. Do not adjust your dose without medical advice, and use the lowest effective dose for the shortest period necessary.

Shelf Life

Synflex 275mg Tablet should be used within the shelf life stated on the packaging when stored correctly and unopened; check the expiry date before each use and discard tablets that have expired.

Storage Instructions

Store below 30°C in a cool, dry place away from direct sunlight and moisture, in the original packaging. Keep out of reach and sight of children.
